Donough and State ,of illinois, have, invented certain newvand useful Improvements in Window-Ventilators, of which the following is a specification.v

"This inventionrrelates to certain lnew and.

usefull improvements inwindow ventilators and hasamong its Amain objects to provide a device of this character which is extremely simple in plan of construction, althougheff fective in operation as ivell as durable and cheaply and easily manufactured.

A further object ofthe invention is to provide `a windowventilator which may be readily vsecured in position `and which is provided with a pluralityof movable'glasspanels having a novel and improved operating means connected therewith, suitable means beingl` provided to retain the operating means inadjusted positions so asf to vary the Ventilating effects obtained.V

Astill furtherobject ofthe inventionlis to provide a ventilator which will not very materially prevent the view Vof objects outside of a dwelling from the interior therei of and which includes Vafplur'ality of mov-I able panels which maybe opened'if de.-

sired to obtain the desired ventilationK al' v through the breeze may be moving from difl ferent directions.

Vith` the above general objects in view and others that will become apparent as thenature of the invention is better understood, the same consists in the novel con-ly struction, form and arrangement of parts,

hereinafter more fully described,.shown in the accompanying drawing and claimed.

In the accompanying drawing formingr part of'vthis applicatiomwherein like characters of referencerefer to lcorresponding parts throughout the several views, i

The upper ends 'the bars are connected '.byva'l horizontal `barl) n connectedby a rearwardly upwardly incline i c bar 20 which is similar to the bar 21 ,whichffgv and lll-'` v The spaces between the'bars '17,17 at one side of the device are.` closed by suit' able horizontally lswinging' hingedfjgla's panels 22 which are similar to the panel 23 which` closev the spaces at the'fopfpo Thespacesbetween bars 5,",16and`1 'ar closed by glass' panels 24 and 215whic'ln a as to swing. rearwardly and upwardlyfas clearly indicated in Figs. 1'vand`2. 'c

An inclined glass panel 26 is hingedat it lowerffo'rward longitudinal edge 27 to the".n barili? to close-the space .at the top oftheia device and .whereby the panel 26 maybe 'swung .upwardly and forwardly to an open 11(Z position as shown in Fig. 2. Suitable turn buttons 28 are provided for the panels 22 V and 23. to maintain the same closed.

In order to operatively swing the panels 524, 25 and 26 from a point within a dwelling metal binding-orfedge protecting strip 25V to which is secured a pivot lug 26 adapted forconnection to the free end 29 of the link 30 of the adjusting arm, whichlink 30 is in turn pivotally connected as at 31, to a second link 321er the adjusting arm. The inner or free end ofthe link 32 is pivotally .mounted upon the shank of the .bolt 33 which is suitably fastened to the'adjacent inside face of the window frame A by suitable screws 34. A hand wheel or nut r35 is threaded upon the bolt 33Vand has ahub portion 36 adapted to frictionally engage the adjacent portion of the link 32so as to effectively maintain the link 32`against pivotal movement to 'thereby maintain the anel connected thereto'in its openedor close adjusted posit-ion.` ff

It is to be understood that, as clearly. in-

dicated in Fig. 2, the links 30 and 32 are substantially Ain the form of toggle levers which arev broken lto open the panels 24 and 25 which swing" inwardly and which are straightened to open `.the panel 26 which swings outwardly. .l

From the foregoing description, it is believed -thatthe construction and-operation of the present invention is readily understood, it being noted that the panel 10 may be removed at any time to receive articles therethrough from a person outside of a dwelling and for any` purpose to which the same may be put, while if the breeze is blowing toward that side of 4the'vdevice which is situated at the right hand side of Fig. 1, the panels 22 maybe opened to allow the breeze to enter the window andthe room provided there- 4with. On the other hand, if the breeze is blowing n the opposite' direction panels 22 may be c osed and the panels 23 opened for like results. Y

In case the breeze is blowing directly toward the panels 24 and 25, the same may bev opened and in order to insure forv proper es; cape of warm air `the panel 26 may be 0011! patent may be obtained for opened, it being a well established fact that the heated air will be mostly 'ound at the top of the ventilator.

As practically the entire present device is formed like a show-case of glass panels, the same does not in any way obstruct the view of persons from the inside of the dwelling and does notdetract from the neat appearance of the dwelling equipped with the same.

The adjusting arms may be readily swung to the desired positions with little eii'ort as well as quickly secured in such positions by manipulation of the wheels or nuts 35 and the links 30 and 32 are positioned so as to be entirely1 out of the way when in use.

Any suitable means may be provided to attach the present device in position, but as the same does not form part of the present invention, no mention of a specific means therefor is made.

While the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless to be understood, that minor changes vmay be made in the form, combinationand arrangement of parts without departing a from Athe 'spirit and scope of the inventlon as claimed.

What I claim v` as new is:

1.V A window i ventilator including a frame-like casing, an inwardly and upwardly swingable panel in the front of said casing normally disposed in a vertical plane when closed,` manually operable means to open said panel including a pivoted link, and means tomaintain said link against pivotal movement to retain the panel in ad' justed open positions.

2. In a window ventilator, a hinged panel, a link having one end pivotally connected to said panel, a second link having one end thereof pivotally connected to the other end of the first named link, a frame, a bolt fastened to said frame, said second lin-k having its other end pivotally mounted on said bolt, and a nut threaded on said bolt adapted to frictionally engage the adjacent end of the second link to maintain the same against pivotal movement to thereby retain the panel in open adjusted positions.

3. A window ventilator including a frame, upper and lower hinged glass panels in the front of said frame, said panels being inwardly swingable to open positions, an outwardly swingable inclined glass panel in the top of said frame, and means to adjustably maintain said panels in open positions.

j In testimony whereof I aiiix my signature.
